I've kept kuhlis with yoyos, striata, and clown loaches, and they were all fine together.
In a larger setup kuhlis are likely to hide whether or not there are bigger loaches. It's just what they do. The only way I saw mine was to look underneath the tank (it was barebottom) and see them sitting under the driftwood, though they did come out to eat.
Kuhlis won't really interact with the larger loaches. They exhibit different behavior.
Cories are fine with loaches. They pretty much just ignore each other.
